Mexico 1790-Mo FM 1/2 real KM-71
Shown is an 1790MoFM half real, one of a type struck 1790 only. The bust of Charles III was used 1789-90 but with the ordinal of the new king, Charles IV. Two varieties exist for 1790; KM 70 with obverse legend "CAROLUS IV" and this one with "CAROLUS IIII." Assayer FM is recorded for the years 1785-1801. The half real, as one-sixteenth of a dollar, would have traded in the United States for 6½¢. Harris notes that the Mexico City half real is the only mint that can be called abundant for Charles III, the second mint, Potosi, is less than half as common.
